regmiller 0 Posted March 8, 2017 I have an older system at my house of 6 cameras. Each camera is wired with a cat 6 cable with a 12v DC supply. I would like to replace the cameras with HD using the same wiring. What adapter do I need to do this. All cameras go to a DVR. Thanks Reg Share this post Link to post Share on other sites
jeromephone 6 Posted March 9, 2017 guessing you have baluns on the orginal cable you would just need to terminate the cable with either a cat 6 jack or a RJ45 plug. I find the jacks work better but that does require a patch cord. Test and use the same pattern on both ends Usually B these days. Share this post Link to post Share on other sites
regmiller 0 Posted March 10, 2017 Thanks Jerome. So I don't need an interface to use the coax for HD. Share this post Link to post Share on other sites
